'Opinion by
¶ 1 This ease involves a juvenile court adjudicating an infant child, A.W., dependent and neglected. A.C., the mother of A.W., tried her case to a jury, which found that A.W. lacked proper parental care and that A.W.'s environment was injurious to her welfare.
T 2 On appeal, mother challenges the order of adjudication, She contends that the court committed reversible error in (1) denying her motion to continue the adjudicatory hearing; (2) permitting the Mesa County Department of Human Services (Department) to introduce evidence about her prior dependency and neglect case in violation of People v. Spoto, 795 P.2d 1314 (Colo.1990); and (8) denying her motion for a new trial.
1 3 We reject each of mother's contentions and affirm.
I. Adjudicatory Proceedings
¶ 4 The Department obtained an emergency custody order concerning A.W.-who was in the neonatal intensive care unit at a local hospital due to respiratory problems-the day after A.W.'s birth. At the time, mother was homeless and had an active warrant for her arrest on welfare fraud charges.
T5 Mother had eight children before A.W. Her parental rights to her seven oldest children had been terminated, and she maintained only limited, supervised visitation with the youngest child, who lived with his father.
T6 On May 12, 2014, the Department filed a petition in dependency and neglect, alleging that A.W. lacked proper parental care and her environment was injurious to her welfare. 'Mother denied the allegations in the petition and requested an adjudicatory hearing. Mother's ability to parent would obviously be a focal point of the hearing.
T7 In preparation for the hearing, mother listed J.L. on her proposed witness list. Mother met J.L. at a homeless shelter, While there, she claims J.L. helped her create a food log in preparation for A.W.'s birth. , And J.L. witnessed her caring for her eighth child while they were at the shelter.
T8 Meanwhile, the Department filed a notice of intent to introduce evidence surrounding mother's prior dependency and neglect case. The Department sought to use this evidence to show the prospective harm to A.W., if she were left in mother's care without its involvement. Mother objected, arguing that this evidence was dissimilar and too remote in time, and did not meet the standards for admissibility under Spoto. After it found evidence that mother's prior involvement with the Department met the standards for admissibility under Spoto, the court ruled this evidence was admissible, subject to a limiting instruction.
_T9 On June 18, 2014, at a pretrial conference five days before the adjudicatory hearing, mother requested a continuance because J.L. was not available. Mother did not have J.L. under subpoena, and the record does not reveal whether mother knew when or if J.L. would be available, Although mother did not provide a transcript of this hearing, the minute order shows that the juvenile court determined there was not "good cause" to continue the adjudicatory hearing.
¶10 At the adjudicatory hearing, the jury heard extensive evidence regarding mother's *787past treatment of her older children-which led to her parental rights being terminated-including that she threw a phone at one child and failed to seek medical attention for the resulting injuries; that she left her younger children in the care of her eight-year-old son for at least an hour and a half; and that at least three of her children failed to thrive under her care. Before the jury heard this evidence, the juvenile court instructed the jury that "in certain instances, evidence may be admitted for a limited purpose only" and that the testimony from witnesses who spoke about mother's prior adjudications "may be used as evidence for the purpose of showing [A.W.] lacks proper parental care and/or her environment is injurious to her welfare, but . should not [be] consider[ed] ... as evidence for any other purpose." As noted, the jury found that A.W. lacked proper parental care and was subject to an injurious environment.
¶ 11 After the jury's verdict, mother filed a motion for new trial, 'Although she claimed that the Department stated or misstated facts not in evidence during closing arguments, she did not file an affidavit or court transcript supporting her claim. In response, the Department argued, among other things, that the motion should be denied because "[albsent an affidavit in support of Respondent's request for a new trial, the [clourt is under no obligation to act." The court denied mother's motion.
¶ 12 Based on the jury's findings, the court adjudicated A.W. dependent and neglected. At a subsequent dispositional hearing, the court adopted a treatment plan for mother,
IIL - Continuance
¶ 18 We first consider whether the juvenile court erred in denying mother's motion to continue the adjudicatory hearing. We conclude it did not.
¶14 Two different standards guide our analysis. On the one hand, if the child is under six years of age at the time a petition is filed, section 19-8-505@8), C.R.8.2015, provides that a continuance of the adjudicatory hearing beyond sixty days after service of the petition may be granted only on a finding that the continuance is in the best interests of the child. It states:
' Adjudicatory hearings shall be held at the earliest possible time, [but] ... if the child is under six years of age at the time a petition is filed ... in no instance shall such hearing be held later than sixty days after service of the petition unless the court finds that the best interests of the child will be served by granting a delay.
On the other hand, Chief Justice Directive 96-08, Directive Concerning the Processing of Dependency and Neglect Cases, § 4 (December . 1996) (hereinafter CJD) provides . that all continuances "will be granted by a Judicial Officer only upon a finding that a manifest injustice would occur in the absence of a continuance."
115 Whether to grant a continuance based on the best interests of the child or manifest injustice standard is necessarily a matter entrusted to the juvehile court's discretion. We thus review a. juvenile court's ruling on a motion for a continuance for an abuse of that discretion. C.S. v. People, 83 P.3d 627, 688 (Colo.2004). ‘
¶16 Although she did not cite the CJD, it appears that mother's request was made under section 4's manifest injustice standard. Her continuance was made within sixty days of service of the petition 'and her request was based on her need to present favorable evidence about her capacity to parent and to rebut the Department's evidence about her prior dependency and neglect case.
117 When a party seeks a continuance of an adjudicatory hearing,. section 4's manifest injustice standard may conflict with section 19-8-505(8)'s best interests of the child standard. But, we do not need to determine if they do in this case. When a motion for continuance is based on the absence of a witness, there is no abuse of discretion in denying the motion if the party seeking continuance did not use due diligence to procure the presence 'of that witness, People in Interest of D.J.P., 785 P.2d 129, 131 (Colo.1990); see also Bigler v. Richards, 151 Colo. 325, 331, 377 P.2d 552, 555 (1963); Durham v. Wilson, 68 Colo. 430, 431, 190 P. 525, 525 (1920). The party requesting the *788continuance carries the burden to show that he or she used due diligence. People in Interest of D.J.P., 785 P.2d at 132. Placing the burden on the moving party to show due diligence is appropriate given the expedited nature of adjudicatory hearings. See § 19-3-505(8) (Adjudicatory hearings shall be held at the earliest possible time.").
118 Mother requested the continuance and thus had the burden to show that she used due diligence to locate J.L. However, because she did not include a transeript of the hearing where she requested the continuance, and because the judge did not grant her request, we must assume that she did not make the proper showing. See People v. Ullery, 984 P.2d 586, 591 (Colo.1999) ("If the appealing party fails to provide us with ... a complete record, we must presume the correctness of the trial court's proceedings."). Accordingly, we conclude that the juvenile court did not abuse its discretion by denying her motion.
III. Admissibility of Evidence of Mother's Prior Dependency and Neglect Case
¶ 19 We next consider whether the juvenile court erred in permitting the Department to introduce evidence about mother's prior dependency and neglect case in violation of poto, 795 P.2d 18314, We conclude it did not, but for reasons other than those relied on by the juvenile court.
120 In Spoto, our supreme court determined the limitations on the admissibility of prior bad acts. The court applied a four-part analysis.
First, we must ask whether the proffered evidence relates to a material fact, le., a fact "that is of consequence to the determination of the action." CRE 401, If it does, we proceed to the second question: is the evidence logically relevant, le., does it have "any tendency to make the existence of [the material fact] more probable or less probable than it would be without the evidence?" CRE 401. If the evidence is logically relevant, we then must determine whether the logical relevance is independent of the intermediate inference, prohibited by CRE 404(b), that the defendant has a bad character, which would then be employed to suggest the probability that the defendant committed the crime charged because of the likelihood that he acted in conformity with his bad character. See CRE 404(b). Finally, if the proffered evidence survives the first three parts of the analysis, we must assess whether the probative value of the evidence is substantially outweighed by the danger of unfair prejudice. CRE 403.
Id. at 1818 (some citations omitted).
121 In ruling that the evidence of mother's prior dependency and neglect case was admissible, the juvenile court addressed the four Spoto prongs. In mother's view, the court erred in so ruling because evidence of her prior parenting was unrelated to her ability to parent A.W. and was thus prohibit, ed by CRE 404(b). We disagree with mother and -conclude that neither CRE 404(b) nor Spoto apply to this prospective harm case. We reach this conclusion because evidence. of mother's past treatment of her older children was not introduced to suggest that she acted in conformity with that treatment in parenting A.W. That is, no prior acts could have established how mother treated A.W. because mother never had custody of her. Rather, the evidence showed the home environment and potential parental care A.W. might be exposed to if she were placed in mother's care. Compare CRE 404(b) ("Evidence of other erimes, wrongs, or acts is not admissible to prove the character of a person in order to show that he acted in conformity therewith."), with People in the Interest of S.N., 2014 COA 116, ¶ 17, 338 P.3d 508 ("Prospective harm ... requires a prediction of whether, based on the parent's past conduct and current circumstances, it is likely or expected that the parent will fail to provide proper care for the child in the future.").
122 Because A.W. had not been in mother's care, the jury was required to determine whether AW. was dependent and neglected based on a prediction of the home environment to which A.W. might be exposed. if she were placed in mother's care, The use of mother's prior acts to make this prediction was relevant to the jury's assessment of AW's status, As our supreme court in Peo*789ple v. DA.K., 198 Colo. 11, 15, 596 P.2d 747, 749-50 (1979), explained:
A proceedmg to determine Whether a, child is dependent or neglected is designed to determine the child's status or situation at the time of the adjudication ,...; However, the child's situation on the day of the hearing cannot be viewed in a vacuum. The evidence of alleged instances of abuse and parental neglect relied upon to establish the child's dependency and neglect must be considered in the context of the . parent's prior behavior.
~ € 238 Accordingly, because mother's acts in a prior dependency and neglect case were used to predict whether A.W. would be exposed to an injurious environment, and were relevant to the jury determining A.W's status as dependent and neglected, neither CRE 404(b) nor the four-part Spoto test applies to this case. ‘
124 Even so, mother contends that the introduction of evidence of her prior dependency and neglect case was madmlssflole under CRE 408. We disagree. _
125 CRE 408 allows relevant evidence to "be excluded if its probative value is substantially outweighed by the danger of unfair prejudice." Unfair prejudice occurs when evidence has a tendency to suggest a decision on an improper basis. See Koehn v. R.D. Werner Co., Inc., 809 P.2d 1045, 1048 (Colo.App.1990) ("[PJrejudice which calls for exclusion is given a specialized meaning: an undue tendency to suggest decision on an improper basis, commonly an emotional one, such as bias, sympathy, hatred, contempt, retribution or horror."). . A
126 We have already concluded that the evidence surrounding mother's prior dependency and neglect case was relevant to the jury's consideration of the home environment to which A.W. might be exposed if she were placed in mother's care. It is well established that the Colorado Rules of Evidence strongly favor the admission of relevarit evidence. See CRE 402; People v. Czemerynski, 786 P.2d 1100, 1108 (Colo.1990).
127 We also. noted that the juvenile court instructed the jury to consider the evidence of mother's prior dependency and neglect case "for the purpose of showing [A.W.] lacks proper parental care and/or her environment is injurious to her welfare, but . not ... for any other purpose." And it is well established that, "absent evidence to the contrary, we presume that a jury follows a trial court's instructions." Qwest Servs. Corp. v. Blood, 252 P.3d 1071, 1088 (Colo. 2011). Béeause mother has not indicated how the jury did not abide by this limiting instruction, and the evidence surrounding her prior case was not so prejudicial that the jury could not follow this instruction, see Perez v. People, 2015 CO 45, ¶ 43, 351 P.3d 897, we assume the jury did not consider mother's prior acts for an improper purpose. Accordingly, we conclude thére was no unfair prejudice and the evidence was not prohibited by CRE 403.
IV. New Trial
128 We last consider whether the juvenile court erred by denying mother's motion for a new trial: We conclude it did not.
129 The question of whether a new trial should be granted is within the sound discretion of the juvenile court. Mayer v. Sampson, 157 Colo, 278, 282-83, 402 P.2d 185, 188-89 (1965). We review only for an abuse of discretion. Id.
¶130 Mother contends that the division's decision in Park Stations, Inc. v. A.C. Hamilton, 38 Colo.App. 216, 554 P.2d 311 (1976), relieves her of her obligation to file an affidavit under CRCP. 59(d)(G). We disagree. In Park Stations, the division held that a trial court could grant a motion for a new trial absent an affidavit, Id. at 219, 554 P.2d at 318. But, that holding does not indicate that the court must grant a motion absent an affidavit. On the contrary, the division stated, "upon receipt of a motion for a new trial on those grounds which, according to the rules, must be supported by affidavit, the court is not required to act in the absence of such affidavit." Id.
¶31 Because C.R.C.P. 59(d)(1) requires a motion for new trial to be supported by affidavit and mother's motion was not, we *790conclude that the juvenile court did not abuse its discretion by denying her motion.
V. Conclusion
¶ 32 The order adjudicating AW. dependent and neglected is affirmed.
